Base excess is a measure of the amount of excess or deficit of bicarbonate in the blood, which helps indicate the presence of metabolic acidosis or alkalosis. It is calculated by measuring the pH and levels of carbon dioxide and bicarbonate in the blood. Negative values indicate metabolic acidosis, while positive values suggest metabolic alkalosis.
To determine if acid or carbonate was in excess initially, you can titrate the reaction mixture with an appropriate base of known concentration. The point where the base completely neutralizes the acid will indicate the amount of acid present initially. Any excess base after this point would suggest that the initial excess was in the carbonate.
To calculate the excess moles of acid in a titration, subtract the moles of base used from the initial moles of acid. This will give you the amount of acid that was not neutralized by the base and therefore the excess moles of acid present in the solution.
To remove excess base after forming a soluble salt from an acid and an insoluble base, the solution must be filtered. This process will separate the insoluble base from the soluble salt solution, allowing you to obtain a pure solution of the soluble salt.
Yes, OH is acidic. That is why it usually has a (-) above it. The single +1 hydrogen doesn't make up for the -2 charge of Oxygen. Making the hydroxyl ion acidic.
Rennies are basic rather than acidic, this is because in their recent advert it shows that rennies turns any excess acid into water. Therefore to do this, a base must be added to neutralise the acid. I hope this helps clear things.

To calculate the excess moles of acid in a titration, subtract the moles of base used from the initial moles of acid. This will give you the amount of acid that was not neutralized by the base and therefore the excess moles of acid present in the solution.
Solid soap typically contains excess base, which is a result of the saponification process where fats or oils react with an alkali, usually sodium hydroxide. This excess base can contribute to the soap's alkalinity, influencing its cleaning properties. However, the amount of excess base is generally minimal and balanced to ensure the soap is safe for skin use. Properly formulated soaps are designed to be mild and effective without causing irritation.
To remove excess base after forming a soluble salt from an acid and an insoluble base, the solution must be filtered. This process will separate the insoluble base from the soluble salt solution, allowing you to obtain a pure solution of the soluble salt.
